expand (1,2,-3)X(-1,1,1)

expand

(1, 2, - 3) X (- 1, 1, 1)

1 \cdot (- 1 \cdot 1 \cdot 1,,) X, 2, - 3 (- 1 \cdot 1 \cdot 1,,) X

Solution steps

(1, 2, - 3) X (- 1, 1, 1)

= (1 \cdot 2,, - 3) (- 1 \cdot 1 \cdot 1,,) X

Apply the distributive law:

a (b - c) = ab - a c

a = X (- 1, 1, 1), b = 1, 2,, c = 3

= X (- 1, 1, 1) \cdot 1, 2, - X (- 1, 1, 1) \cdot 3

= 1 \cdot (- 1 \cdot 1 \cdot 1,,) X, 2, - 3 (- 1 \cdot 1 \cdot 1,,) X

(1 2_{2} - 1 5_{1})^{2}

- 2.07 - (- 8.6)

(1 - e^{- 2 x})^{2}

\frac{8 x ( x - 6 )}{( x + 2 ) ( x + 9 )}

(x - 1) \cdot ln ∣ x - 1 ∣
